VEGANS will finally be able to enjoy a pint of the black stuff after Guinness removed fish bladder from its brewing process.
The iconic Irish stout had prevoiusly been filtered using isinglass, a protein derived from dried fish swim bladders.
But in 2015, Guinness announced that they would be reworking their brewing process to remove its only animal product while retaining its famous taste.
Last Friday Diageo, Guinness' parent company announced it was rolling out its vegan-friendly stout.
The change only applies to draught Guinness for the moment, but cans and bottles of the drink will be fish free by the end of this year.
In a statement announcing the news, Guinness said: "The first stage of the roll out of the new filtration system concentrated on Guinness Draught in kegs.
"The brewery is delighted to confirm that this phase of the project is complete and all Guinness Draught produced in keg format at St. James’s Gate Brewery and served in pubs, bars and restaurants around the world, is brewed without using isinglass to filter the beer."
It added: "The recipe for Guinness has not changed and the taste has not changed. It is still the same great pint of Guinness it has always been.
"Through advances in brewing technology, we have identified an alternative process through investment in a new, state-of-the-art filtration system at St. James’s Gate, which removes the need for the use of isinglass finings in the production of Guinness."
The move follows years of campaigning for Guinness to become vegan friendly.
Activists have welcomed the news, with PETA saying on Facebook: "When we learned that Guinness removed isinglass (obtained from fish bladders) from its filtration method, some of us might have shed tears of joy.
"Stout-lovers can raise a glass to the fact that draught Guinness around the world is now vegan."
